We're not saying the U.S. needs to enter another war anytime soon, but should the nation's armed forces find themselves in a situation where new recruits are few and far between, this inflatable boot camp obstacle course will easily bolster its numbers.

Which would you prefer? An uptight drill sergeant screaming in your face while you do push-ups in the rain, or a giant bouncy slide? Crawling through the mud under razor wire, or a rope swing over a few inches of water? If this were standard issue at every military base, even hippies would be lining up to serve their country. And that $12,500 price tag? That's paltry compared to what the Air Force already pays for fighter planes that barely seem to work. [Hammacher Schlemmer via The Green Head]
